I can understand choosing the PS4 in order to not deal with unplayable shit-ports like Skyrim, but what you are doing, is shitting on developers, because they want the game to run according to their specs on all platforms and not let one platform left behind like in Skyrim. So if Batman runs equally on both platforms, and it also runs well on both platforms, there is nothing rational to complain about from my perspective. And from what I've played at Gamescom, Batman already was running very well and looked great, so if they manage to polish it even more for both platforms, we will end up with a great looking, great running game (that also seems to shape up to be a great game, too, by the way).
So what I see here is a sort of mean sense of entitlement, where you don't just want developers to not make any shit versions for PS4 like Skyrim was, but to focus on the small extra potential PS4 has to offer over Xbone and intentionally aiming the game at a level Xbox One cannot reach properly. In other words: It reads to me, as if you are not hapy as long as the Xbox One version has not disadvantages, even if the game runs perfectly fine on both consoles, just cause. This, form my perspective, is the absolute worst kind of console warrior behaviour and I just cannot understand that this is tolerated so much. Of course, if the game is done, running perfectly fine on both systems and then there is something they can do to make one version look a bit better without much hassel and without any imposed disadvantages, the developers should apply this, but that need not be the case all the time and it doesn't change that developers should first focus on making it run equally well on all platforms.
I'm sure that if Batman was just releasing on PS4 the same way it will be if it realy has parity with Xbox One, just without an Xbox One version, every PS4 user would be super happy, but just the existence of an equally well made Xbox One version makes you rage (something that never happend, from my perspective, with Xbox 360 users, everything was fine when both versions ran and looked fine). This kind of inverse jealousy is despicable.
